Istarted out with 2 volunteers,female and now have 50 more up to 12 ft that must be male.Is there a reason why only males are showing up.
What kind of Holly? Opaca? Do you want more females? I think you do not need any more for fertilization.
I didnt plant any so I dont know what kind.It fits your description,leaves about 2 in long,16/18 spines per leaf.If Idecide to keep some of them I would like to have some berry production.Thanks. Ken.
